Precast headwall with dovetail slots and handrail

Althon Precast headwalls are a cost-effective alternative to in-situ concrete structures for connecting pipework discharging into open watercourses. All drainage pipes discharging into open watercourses such as swales, ditches, ponds and rivers should be fitted with an appropriate headwall. Althon headwalls can be factory-fitted with accessories such as flap valves, penstocks, gratings, V-notch weirs, access gates, ladders and steps, and Kee Klamp® or GRP handrails.

• Sewerage Sector Guidance (Sewers for Adoption) compliant headwalls Where a headwall is part of a Section 104 Agreement and the sewers are to be adopted once completed by the local water company, the materials used and the installation must comply with Sewerage Sector Guidance. Althon has a range of precast concrete headwalls to comply with these requirements.

• Rectangular Sewers for Adoption headwalls (RSFA) Althon rectangular precast concrete headwalls are designed to meet STW headwall requirements. The toe extensions are available in 300 and 500mm thicknesses, each of which is available in three depths. RSFA headwalls are manufactured with three wingwall profiles to suit the gradient of the bank: 1:1, 1:2 or 1:3 slopes.

They are typically supplied with a Kee Klamp® handrail to the back wall and horizontal sections of the wingwalls, a galvanised steel access ladder, and a self-closing gate with padlock facility. They can also be supplied with stepped baffle blocks to dissipate water discharging onto the spillway.

• Bespoke headwalls Althon designs and manufactures bespoke headwalls to suit site-specific circumstances.

These can either be one-piece units or sectional structures where the headwall is very large.

They can accommodate gratings, flap valves, trash screens and other security or flow control devices, as well as health and safety essentials such as handrails, walkways and step ladders.

Chieftan chamber with penstock and actuator

Althon offers flow control and flood prevention products that can be used in surface, sewer and process water applications.

• Flap valves Flap valves are a simple and effective way to prevent water backflow into a system. For heavy duty applications, 100–1500mm flaps are made with additional features such as welded stiffening ribs. They are manufactured in a combination of HDPE/316 stainless steel meaning they are lightweight and high in strength. They are easy to install, responsive and reliable. Althon can also supply cast iron flap valves.

• Penstocks HDPE penstocks are a simple and effective way to isolate and regulate water and levels. Designs have been developed to accommodate the majority of situations where a penstock is required. They are suitable for sealing pressures of 5mWC as standard, require virtually no maintenance and are fast, safe and easy to install.

• Stop logs Stop logs are used for the isolation and containment of water and controlling water levels. Lightweight and corrosion-resistant, they are suitable for applications where standard single-piece stop gates would be too heavy to lift.

Stop logs are manufactured using the latest materials combined with aluminium or stainless steel, and can be provided fitted to precast headwalls or as standalone products with different mounting arrangements.

• WaStop Valves WaStop valves can be installed inline between two pipes to prevent backflow or, more typically, in a manhole. They are made from 316 stainless steel or PVC tube and incorporate a cone-shaped membrane. The membrane allows water flow to pass in the desired direction but when backflow occurs the membrane fills and seals the pipe. As the WaStop does not rely on gravity to close the membrane it does not need to be fitted against a vertical headwall. They are suitable for water pressures up to 8mWC.

Stop logs can be factory-fitted to headwalls

In addition, Althon can quote for bespoke gratings.

• Outfall safety grilles Althon outfall and safety grilles are compliant with Sewerage Sector Guidance. The Sewers for Adoption and Sewers for Scotland guidelines for gratings and trash screens call for an outfall safety grille to be fitted to any headwall with a pipe opening of 350mm or greater. The guidelines specify that the grille must be a minimum of 270mm wider than the outside diameter of the pipe, have bars at 100mm spacing, be hinged and have a padlock facility. Standard gratings and trash screens are hot dip galvanised to BS EN 1461 but are available in stainless steel if required.

• Sloped trash screens Althon sloped trash screens are designed to fit to precast, in-situ or brick headwalls and outfalls.

They reduce the amount of trash, litter and natural debris entering pipework and culverts whilst also preventing unauthorised access and blockages. Althon can manufacture the screens at either 45 or 60 degrees with and without sides.

Screens can also be designed and manufactured to customer specifications.

• Vermin grilles Vermin grilles are designed to prevent rodents and other vermin entering connecting pipework.

They are designed to be fitted to any flat surface or to an Althon precast concrete headwall.

66 WATER RECYCLING

EXTERNAL WORKS SDS Limited Drought mitigation SDS water reuse systems help protect declining natural water supplies and enable new developments to achieve the goal of being water neutral. The systems also reduce the impact of increasingly frequent and intense rainfall events on the sewer network. Instead of heavily treated, mains-supplied drinking water, non-potable water supplies such as collected rainwater and grey water can be used for flushing toilets, washing cars or irrigating gardens.

• Grey water recycling SDS’s innovative grey water treatment system makes it simpler and more cost-effective for developments such as smaller hotels, residential and commercial buildings to operate lowmaintenance grey water recycling. The all-in-one, pre-fabricated, skid-mounted system can also be easily retrofitted into existing buildings where space is at a premium.

• Rainwater harvesting SDS’s Intellistorm® system replaces a traditional water butt with an intelligent storage tank which analyses weather forecasting information in order to predict rainfall. Whilst it is programmed to maximise the volume of captured rainwater for reuse, the system discharges to the sewer network sufficient of the tank’s contents to accommodate the forecasted rainfall.

StableTRUCK Grasspave – close-up detail

StableGRASS gravel reinforcing grids and StableTRUCK Grasspave heavy-duty grass pavers provide naturally permeable paving options. The products cover all applications from simple green pedestrian and light vehicle access to heavier duty surfaces for commercial and constant use.

• StableGRASS grass grids StableGRASS offers two panel sizes in both 38 and 50mm depths. Available in Green and Black as standard with Buff Dolomite produced to order, the range is flexible, covering almost all potential applications. All grids are fully interlocking, very robust and secure, whilst the cell design creates free space for root development.

StableGRASS MAXI is the flagship grid. Large dimensional panels of 1.2x0.8m can be laid in a brick bond pattern, giving enhanced stability and enabling significant productivity gains on larger installations. Standard light to medium use will require the 38mm depth, whilst more regular vehicular requirements need 50mm.

StableGRASS 38 and StableGRASS 50 are supplied in more traditional 50x50cm panels, where that is a preferred option. Compressive load resistance is similar to StableGRASS MAXI. • StableTRUCK grass pavers StableTRUCK Grasspave is a heavy-duty paver for use with grass or granular fill.

It is an economic and secure paving option for access, parking and storage by commercial vehicles, coaches, maintenance plant and fork lift service yards. Other applications include grass verges, laybys, passing places and hard standings.

Two versions are available: – Grooved top surface to give audible indication of vehicle transit.

– Flat top surface for comfortable pedestrian access.

Manufactured incorporating specially selected and graded recycled raw material, StableTRUCK has excellent environmental and sustainability characteristics. Material is fully recyclable at end of life.

Free-draining permeability can be achieved by the use of suitable granular material, potentially forming part of a fully permeable paved structure.

The pavers are produced as interconnecting tiles of 60x40x10cm-deep on a cell matrix of 12cm; 12cm-deep tiles are available on special order.

Compressive load resistance has been independently tested, with results confirming a capability of +/- 500 T/m2 when filled (test certification available on request).

HRL has been producing reinforcing grids for gravel paving for 20 years, and continually improves and develops its products. The range has evolved to cover all applications from pedestrian-only pathways to heavier duty, constant use areas.

Products are designed to prevent rutting, sinking and migration of gravel, whilst adding loadbearing reinforcement to the pavement construction. Being simple and very fast to install makes the paving extremely cost-effective.

Systems provide a naturally permeable paving surface, largely eliminating the water run-off created by hard surfaces, reducing demand of surface water drainage capacity, adding to environmentally sustainable credentials.

Grids are produced and supplied in 1.2x0.8m panels and have a robust weed-suppressant membrane attached to the base.

• StablePATH 22 is a 22mm-deep white grid for pedestrian-only applications, such as pathways, terraces, roof gardens and communal access.

• StableDRIVE 30 and 40 white grids are available at 30 and 40mm deep for residential parking and paving. They are suitable for all light vehicles and occasional access by heavier traffic such as utility and emergency trucks.

• StablePAVE HD pro fully interlocking dark grey 38mm-deep panels are suitable for heavier duty applications such as constant use car parking, access roadways, plant storage and any situation where regular turning with high point loading, such as small wheeled horse boxes and trailers, is likely to occur and the added lateral load resistance will be beneficial.

StablePATH 22 for pathways and roof gardens

Composition and manufacture All grids are manufactured using specially selected and largely recycled raw material and are UVresistant. They are fully recyclable at end of life making them exceptionally sustainable.
